[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a double-ended wrench for tightening bolts, screws, nuts and other threaded fasteners.

[0030] The double-ended wrench includes a main shaft 1, an internal hex wrench 2, and an external hex wrench 3. The main shaft 1 includes a long shaft 11, and short shafts 12 and curved shafts 13 connected to both ends of the long shaft 11. The short shaft 12 is perpendicular to or intersects the long shaft 11, and the curved shaft 13 is bent away from the side opposite to the short shaft 12. Thus, the short shaft 12, long shaft 11, and curved shaft 13 are all on the same plane, forming an approximately Z-shaped structure, allowing for gripping at both ends and facilitating the application of force. Optionally, the main shaft 1 is made of a high-strength, lightweight material. The long shaft 11 is 300mm long and 12mm in diameter, ensuring sufficient rigidity while preventing interference in confined spaces due to its excessive size.

[0031] One end of the internal hex wrench 2 is connected to the short rod 12. The extension direction of the internal hex wrench 2 is parallel to the extension direction of the short rod 12. This allows the internal hex wrench 2 and one side of the short rod 12 to enter narrow spaces after engaging with the main rod 1. It also facilitates applying force through one side of the curved rod 13 to provide sufficient torque to the internal hex wrench 2, ensuring that the threads do not strip or damage components during loosening or tightening. Meanwhile, the external hex wrench… One end of the hex wrench 3 is connected to the curved rod portion 13. The hex wrench 3 has a wrench hole 31, the opening 331 of which is perpendicular to the plane formed by the curved rod portion 13, the long rod portion 11, and the short rod portion 12. Thus, after the hex wrench 3 engages with the main rod 1, the bending of the curved rod portion 13 allows the hex wrench 3 and one side of the curved rod portion 13 to operate in narrow spaces, and facilitates force application through the short rod portion 12, achieving a greater operating range and leverage. This double-ended wrench can be operated in narrow areas, reducing the difficulty of installation or disassembly, improving operating efficiency, and preventing damage to components.

[0032] Furthermore, the side of the external hex wrench 3 away from the crank shank 13 is cut to form a cross-section 32, thus creating an irregular structure for the external hex wrench 3. Specifically, the external hex wrench 3 employs a non-standard, asymmetrical angle and shape design, facilitating avoidance through the cross-section 32, optimizing the contact angle, reducing interference from equipment, improving positioning accuracy, and enabling the main shaft 1 to provide sufficient torque to the external hex wrench 3 while preventing damage to components. Optionally, the external hex wrench 3 is provided with side ribs. These side ribs enhance the overall structural strength of the external hex wrench 3 with the cut cross-section 32, preventing bending or deformation of the external hex wrench 3 due to high torque operation.

[0033] Furthermore, a baffle 33 is provided inside the wrench hole 31. The baffle 33 divides the wrench hole 31 into a first chamber and a second chamber along the radial direction of the wrench hole 31. This allows the operator to use either the first or second chamber to accommodate bolts, screws, nuts, or other threaded fasteners, facilitating the adjustment of the shape or direction of the main rod 1. The baffle 33 also stops and supports nuts, preventing them from falling into the equipment and affecting its normal operation. Additionally, the baffle 33 enhances the overall structural strength of the external hex wrench 3. The baffle 33 has an opening 331 connecting the first and second chambers. This opening allows the operator to easily observe the installation or removal status on the other side of the baffle 33, ensuring the normal use of the external hex wrench 3 during operation. Meanwhile, the opening 331 is located in the middle of the baffle 33, and the diameter of the opening 331 is 5mm. So when the external hex wrench 3 locks the nut threaded onto the screw, the opening 331 can avoid the screw, preventing the baffle 33 from blocking the movement of the screw.

[0034] Furthermore, the double-ended wrench also includes a positioning element. The side wall of the external hex wrench 3 is provided with a mounting hole 34 that communicates with the wrench hole 31. The positioning element is threadedly connected to the mounting hole 34. Thus, after the positioning element rotates and moves within the mounting hole 34, it can abut against or disengage from the component within the wrench hole 31. This achieves positioning of the component within the wrench hole 31, improves the stability of the component within the wrench hole 31, and reduces safety hazards caused by improper size or operation of the external hex wrench 3.

[0035] Furthermore, the cross-sectional dimension of the short rod 12 is larger than that of the internal hex wrench 2. This allows the short rod 12 to abut against the opening of the internal hex wrench 2 when it is inserted into the internal hex hole. This ensures a certain distance between the long rod 11 and the equipment, preventing interference or even damage to the equipment when the main rod 1 rotates. Simultaneously, the curved rod 13 is bent at 90°–100°. After adjustment, the external hex wrench 3 and the curved rod 13 can avoid other internal components of the equipment, achieving a greater operating range and leverage.

[0036] Furthermore, the curved rod portion 13 and the long rod portion 11 are detachably connected by threads, so that the double-ended wrench can be split into two parts after the curved rod portion 13 is removed from the long rod portion 11. This facilitates the storage or transportation of the double-ended wrench. At the same time, in some special cases, such as when the external hex wrench 3 and the curved rod portion 13 interfere with the use of the internal hex wrench 2, the disassembly of the curved rod portion 13 and the long rod portion 11 can solve the interference problem.

[0037] When used in tobacco packaging equipment, this double-ended wrench not only has the ability to disassemble the air intake nozzle, but is also suitable for disassembling the 625-2Z bearing, meeting a variety of maintenance needs and achieving multiple uses in one tool.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
